[例5] 1/4円弧曲りはり。エネルギーで

youtubeの板書です。

>じゃ、最後だ。
途中55:50から (0:00〜1:22:49)

sympyで

・ver0.1

# ver0.1
# [例5] 1/4円弧曲りはり 
from sympy import *
var('P,a,b,EI,θ',real=True)
U=1/(2*EI)*integrate((-P*a*cos(θ))**2*a,(θ,0,pi/2))   #;print('#',U)
δ=diff(U,P)                                             ;print('#',δ)                                              
# pi*P*a**3/(4*EI)

(勉強中) Mathematicaで

(勉強中) MATLAB 追加のオプションSymbolic Math Toolbox で

いつもの? sympyの実行環境と 参考のおすすめです。

(テンプレート)

いつもと違うおすすめです。
